IMPROVEMENT 1N Looms.

lhe Schedule referred to :in these Letters Patent and making part of the Ramo.

To all whom it may corriera Be it known that-I, WILLIAM Rossn'rcrnn, of Aocrington, in the county of Lancaster, England, have invented a new and useful Improvement in Looms; endl do hereby declare that the following is a full, clear, and exact description thereof, which will enable `others skilledlin the art to make and use the same,

reference being had tothe accompanying drawings,

, forming part of this specification.

out stopping-tbe loom, as hereinafter fully set forth.

Figure 1, sheet l, represents a partial front eleva: tion of a loom, provided with my improvements.

Figule l, sheet 2, represents another partial'front elevation. y

'Figure 2 represents a side elevation, showing the means for supplying a fresh shuttle.

Figure 3 represents a side elevation, showing the shuttle when` the weft is broken.

Similar letters of reference indicate corresponding parts.

I support the ordinary weft-fork holder a, upon an arm, b, rising from the transverse shaft o, extending across the loom underneath the breast-beam, andcar-. 7rying at one end a lever, p, andat the other a lever, d,

and arrange the ordinary sector-hammer a in the usual manner for catching the weftPfork when the weft is broken, to oscillate the shaft C.

I provide slotted and movable shuttle-guards, h and h, at eacbend of the lay, and support them on. yokes h, underneath the lay by vertical rods-running through the same, the said yokes being .provided with arms, e' d, projecting downward and supporting friction-bowls at their lower ends in the same plane of .the armsd and p. y

(n represents an arm pivoted at nl, on a bracket projecting downward Afromthe lay, at the dischargingl side ofthe loom.

The upper end of the said lever is connected to a T-headed slide n2, working hrough the bottom of the rear shuttle-guard of the lay, to eject the shuttle.

O represents a lug on the arm p, lwhich is brought into contact with the lower end ofthe arm n, when it is raised by the sector-hammer. A

At the end of the breast-beam on the ejection-side, is a plate or table l for the reeeption'of ,the shuttles having spring-guards l, under which the shuttles-are received, and projections Z, which enter corresponding recesses in tbe shuttle-box when the lay moves up,l andform bridges over which the shuttles pass to the said receiving-table Simi-lar projections may be also formed on the bottom of the shuttle-box, taking into recesses in the said table.

On the supplying-sideof the loom, I arrange on a similar table a `shuttle-case K, capable of receiving any suitable number of shuttles superposed upon each other,

the said case having an opening at the bottom towards the lay, large enough for the bottom shuttle to pass through, and above the said opening spring-guards m, to prevent the shuttle from rising up under the action Vof the forked and-bent lever m, pivoted at m?, to the h frame by which they are thrown upon the lay, bridges being formed at this end similarly to those at the` other.

0n the pivot ai", underneath the lay, I arrange loosely the bent spring-lever f, Vtbe horizontal part of which passes above the yoke h, in a manner to cause the lower end of the said spring-lever to strike theA lower end of the lever m1 when the yoke rises.

When the loom is working, the breakage or absence ofthe .:eft is detected, when the shuttle is returning to the weft-fork end, by the said weft-fork, and when the dftection takes place, the sector-hammer-a' catches the hooked end of the weft-fork, and draws the, arm b back, turning the shaft c, and raising the movable shuttle-guards h and .t

On the delivery-side of the loom tue stud O strikes I the lower end of the arm n, throwing the T-sbaped slide n forward, and ejecting the shuttle which is received on thetable l, under the spring-guards l, where each shuttle is held until the next one follows, driving the lirst forward under the guards, and so on until aA number accumulates to beremoved from time to time.

0n the replenishing-side, the raising of the yoke It by the arm al, raises the spring-lever f, so that the lower end strikes the lower end of the lever m, throwing the upper end against the bottom shuttle, and forcing it on to the lay. As soon as theshuttle is reeeived into the shuttle-box, the friction-bowl at the end of the projection@ of the yoke passes into a recess in the arm al, which allows the shuttle-guard to fall'sufiiciently to prevent the shuttle from being thrown back by any shock, especially that of the commencement of the return motion of the lay.

The said friction-bowl dwells inthe said recess until the shaftc commences its return movement, carrying the arm d downward, and' allowing the shuttle-guard to fall back. Any suitable spiings may be employed for retracting the levers m and n.

lhe ends ofthe thread of the bobbins in the shuttles on the replenishiug-side, may be secured by any suitable means, as the shuttles are placed in the boxes,

to cause themA to wind oli'.

My invention is applicable aliket looms having the ypickers operated from below or above, and to looms generally.=

As it is desirable to prevent the picking-stick on the ejection-end of the lay from making a stroke, until the shuttle has been delivered from the other end, I propose to place on the tappet-shaft t clutch-box, one

balll on the shaft, and the other half fixed to the pickingdgfmgio, and the imlf ofitiiefoitcihbox on the sb aft l. Th slotted and movable Shuttigumds 7l and h, supported on the yokeshz, and combined with the oscillating arms Z :md 11, substantially as speci" fied.

2. The combination with the slotted and'rnovzibie shuttle-.guard h, of the slide n2, and 2mn n, att-ached no the lay with the oscillating zum p, substantially as specified.

3. The receiving-table l, provided with the springs lover ml, and shuttle-box, k, substantially as specified.

Tho shuttle-box 7:, provided with the. spring-guards m, substantially n. Qpecifod.
